Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking. For lighting on one
side for parking as an additional feature, refer to
page84.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, as otherwise it may no longer be
possible to start the engine.<
Low beams
The low beams light up in switch position2 only
with the engine running. Otherwise the parking
lamps are lit.
Automatic headlamp control
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol is
illuminated when the low beams are on.When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
If desired, the light switch can be left in the
position3. The exterior lighting is automatically
switched off after switching off the vehicle.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You can set the duration or deactivate the func-
tion via iDrive.
iDrive, for explanation of principle, refer to
page16.

any time and switch the high beams on and off
in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position3,
refer to page83.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, whereby the system reacts to oncom-
ing traffic and traffic ahead, as well as to suffi-
cient lighting, e.g. towns/cities.
Manually switching between high and
low beams
You can intervene at any time if you wish or the
situation requires.
>If the high-beam assistant has switched on
the high beams, however you nevertheless
want to use the low beams, simply switch to
the low beams with the turn signal lever.
The high-beam assistant is deactivated in
the process.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>If the high-beam assistant has switched on
the low beams, however you nevertheless
want to use the high beams, switch to the
high beams in the accustomed manner. The
system is deactivated in the process and
you must switch to the low beams manually.To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>You use the headlamp flasher as usual with
low beams.
System limits
The high-beam assistant cannot replace
personal decisions on the benefits of
using the high beams. In situations which
require this, you should therefore switch to the
low beams manually to avoid a safety risk.<
In the following example situations, the system
does not operate or only with limitations and a
personal reaction may be required:
>Under extremely unfavorable weather con-
ditions, such as fog or heavy precipitation
>For perceiving road users with poor lighting
of their own, e.g. pedestrians, cyclists, peo-
ple on horseback, horse-drawn vehicles,
with train or ship traffic close to the road and
wild animals crossing the road
>In tight curves, on steep crowns or depres-
sions, with cross traffic or partially con-
cealed oncoming traffic on the freeway
>In poorly lit places and with highly reflective
signs
>In the low speed range
>When the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror
>When the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth moistened with a small
amount of glass cleaner
